DETAILED DESCRIPTION

In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

Reference will now be made in detail to some embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of some embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims.

The inventors of the present application have recognized that in related art, the terminal accesses the webpage through a browser or software including a browser kernel. In order to ensure the security of the operating system of the terminal and the user privacy, the browser and the like create an independent execution environment for the webpage, so that the webpage is isolated from the system of the terminal. In the case of a generic browser, for example, the webpage and the operating system of the terminal can only interact through a preset interface of the browser. However, for functions involving system security and user account information, the generic browser does not have a corresponding preset interface and cannot implement the corresponding function. To implement the corresponding function, specific software with the corresponding preset interface has to be developed based on the browser kernel. Then, when the webpage is accessed through the specific software, the interaction between the webpage and the operating system of the terminal can be completed and the corresponding functions can be realized.

To overcome the problems in the related art, various embodiments of the present disclosure provide a method and a device for information interaction.

For example, when an access request sent by a webpage to a preset domain name is received, the preset domain name is resolved into a designated access address that has not been occupied. The access request with a destination address being the designated access address is redirected by a firewall to a local web service which may interact with the operating system of the terminal. Then, the interaction with the operating system of the terminal is performed by the local web service. Such information interaction process can avoid the limitation of the interaction function between the browser or the browser kernel and the operating system, enable interaction between the developed function of the webpage and the operation system through a generic browser or software based on the browser kernel, which can lower the developing cost and have a wide applicability.

FIG. 1A is a flowchart of a method for information interaction according to some embodiments. As shown in FIG. 1A, the method is applied to a terminal, and includes the following steps.

In step 101A, when an access request sent by a webpage to a preset domain name is received by a browser component, the preset domain name is resolved into a designated access address.

The access request is sent by the webpage when it is required to interact with the operating system of the terminal, and the designated access address is an access address that has not been occupied.

In step 102A, the access request is sent to the designated access address as the destination address.

In step 103A, when a firewall detects that the destination address of the access request is the designated access address, the access request is redirected to a local web service which is configured for information interaction with the operating system of the terminal.

In step 104A, based on the interaction between the local web service and the operating system of the terminal, the access request is responded to and a response message is returned.

In the method provided by the embodiment of the present disclosure, when an access request sent by a webpage to a preset domain name is received, the preset domain name is resolved into a designated access address that has not been occupied. The access request with a destination address being the designated access address is redirected by a firewall to a local web service which may interact with the operating system of the terminal. Then, the interaction with the operating system of the terminal is performed by the local web service.

Such information interaction process can avoid the limitation of the interaction function between the browser or the browser kernel and the operating system, enable interaction between the developed function of the webpage and the operation system through a generic browser or software based on the browser kernel, which can lower the developing cost and have a wide applicability.

In some embodiments, resolving the preset domain name into a designated access address includes the following steps.

A domain name resolution interface of the operating system of the terminal is invoked by the browser component, and the domain name resolution interface has a domain name filtering function; and

the preset domain name is resolved into the designated access address based on the domain name filtering function.

In some embodiments, redirecting the access request to a local web service of the operating system of the terminal includes the following steps.

The destination address of the access request is converted into a local IP address and a local port number according to an address filtering rule of the firewall, and both of the local IP address and the local port number point to the local webpage service; and

the access request with the converted destination address is forwarded to the local webpage service.

In some embodiments, after the access request is responded to and a response message is returned, the method further includes the following steps.

When it is detected by the firewall that a source address of the response message is the local IP address and the local port number, the response message is redirected to the webpage; and

both of the local IP address and the local port number point to the local web service.

In some embodiments, redirecting the response message to the webpage includes:

the source address of the response message is changed to the designated access address according to the address filtering rule of the firewall; and

the response message with the changed source address is forwarded to the webpage.

All of the above optional technical solutions may be combined to form an optional embodiment of the present disclosure, and will not be further described one by one herein.

FIG. 1B is a flowchart of a method for information interaction according to some embodiments. As shown in FIG. 1B, the method is applied to a browser component, and includes the following steps.

In step 101B, when an access request sent by a webpage to a preset domain name is received, the preset domain name is resolved into a designated access address. The access request is sent by the webpage when it is required to interact with the operating system of the terminal, and the designated access address is an access address that has not been occupied.

In step 102B, the access request is sent to the designated access address as the destination address. The access request is subject to address filtering detection by a firewall, and the firewall is configured to: when it is detected that the destination address of the access request is the designated access address, redirect the access request to a local web service for information interaction with the operating system of the terminal, respond to the access request and return a response message.

In the method provided by the embodiment of the present disclosure, when an access request sent by a webpage to a preset domain name is received, the preset domain name is resolved into a designated access address that has not been occupied. The designated access address may be redirected by a firewall to a local web service that may interact with the operating system of the terminal. Then, the interaction with the operating system of the terminal is performed by the local web service, and a response message is returned. Such information interaction process can avoid the limitation of the interaction function between the browser or the browser kernel and the operating system, enable interaction between the developed function of the webpage and the operation system through a generic browser or software based on the browser kernel, which can lower the developing cost and have a wide applicability.

In some embodiments, resolving the preset domain name into a designated access address includes: invoking a domain name resolution interface of the operating system of the terminal, the domain name resolution interface having a domain name filtering function; and resolving the preset domain name into the designated access address based on the domain name filtering function.

All of the above optional technical solutions may be combined to form an optional embodiment of the present disclosure, and will not be further described one by one herein.

FIG. 2 is a flowchart of a method for information interaction according to some embodiments. As shown in FIG. 2, the method is applied in a terminal, and includes the following steps.

In step 201, when an access request sent by a webpage to a preset domain name is received by a browser component, the preset domain name is resolved into a designated access address.

In some embodiments, the preset domain name is a special domain name registered previously. The preset domain name does not point to any webpage. Since the preset domain name is registered, it is generally not occupied. For example, the preset domain name may be “abcdefghijk.com,” which is not limited by the embodiment of the present disclosure.

In some embodiments, when a webpage function is developed, for a function of the webpage that requires interaction with the operating system of the terminal, an access request triggered by the function is directed to the preset domain name. That is, when the webpage is required to interact with the operating system of the terminal, an access request pointing to the preset domain name is sent. That is, for any access request sent to the preset domain name, the terminal determines it as an access request that requires interaction with the operating system.

The designated access address may be preset or modified by the system of the terminal. In the actual application process, the designated access address may not actually exist, and it may be understood that the designated access address is not occupied by any service, application or machine. The designated access address may be an IP (Internet Protocol) address, or a combination of an IP address and a port number. For example, the IP address may be preset to 1.2.4.3 or 255.0.0.0 and the like, which may not be occupied generally or may be an illegal IP address. The port number may be any port number that does not conflict with other services, such as 80, 8080, etc. When the designated access address is a combination of an IP address and a port number, the designated access address may be 1.2.4.3:80, for example, which is not limited in the embodiment.

In some embodiments, when the terminal triggers an access request in a webpage, the terminal sends the access request through a script js, and the access request is processed by a browser component of the terminal. For example, the browser component resolves the preset domain name carried by the access request.

It should be noted that the browser component in this embodiment is configured to implement a browsing function for the webpage, and the browser component may be included in a generic browser, or may be included in software having a browser kernel, which is not limited in the embodiment of the present disclosure.

In an embodiment of the present disclosure, the process of resolving the preset domain name into the designated access address includes: invoking a domain name resolution interface of the operating system of the terminal by the browser component, the domain name resolution interface having a domain name filtering function; and resolving the preset domain name into the designated access address based on the domain name filtering function.

A preset domain name filtering module is provided additionally in the domain name resolution program of the operating system of the terminal, and the preset domain name filtering module is configured to convert the preset domain name into the designated access address. The browser component executes the domain name resolution program of the operating system of the terminal by invoking the domain name resolution interface. In an implementation, the preset domain name filtering module stores a correspondence between the preset domain name and the designated access address. When the domain name resolution program is executed, the preset domain name filtering module acquires the designated access address corresponding to the preset domain name according to the above correspondence, and returns the designated access address to the browser component.

Taking the browser component included in the browser as an example, in the process of displaying the webpage through the browser, when the webpage triggers an access request that requires interaction with the operating system of the terminal, the webpage sends the access request to the preset domain name abcdefghijk.com through the script js. The browser performs domain name resolution on all access requests sent by the webpage. When the browser detects that the domain name of the access request is the preset domain name abcdefghijk.com, the browser invokes the domain name resolution interface of the operating system of the terminal to resolve the preset domain name into the designated access address 1.2.4.3 and return the designated access address 1.2.4.3 as a return value to the browser.

In step 202, the access request is sent to the designated access address as the destination address.

When the browser component acquires the designated access address, the access request is forwarded to the designated access address as the destination address. That is, the destination address of the access request is the designated access address. The detailed process of sending the access request is: acquiring an IP data packet corresponding to the access request, setting the destination address of the IP data packet to the designated access address; and sending the IP data packet based on the set destination address.

Taking the browser component included in the browser as an example, when the browser acquires the designated access address as 1.2.4.3, the IP data packet is sent after the destination address of the IP data packet of the access request is set to 1.2.4.3.

In step 203, when a firewall detects that the destination address of the access request is the designated access address, the access request is redirected to a local web service.

In some embodiments, the process of redirecting the access request to a local webpage service includes: converting the destination address of the access request to a local IP address and a local port number according to an address filtering rule of the firewall; and forwarding the access request with the converted destination address to the local webpage service.

Both of the local IP address and the local port number point to the local web service. That is, the local web service may be accessed through the local IP address and the local port number.

The local web service is configured to perform information interaction with the operating system of the terminal. The local web service may also be regarded as an HTTP (HyperText Transfer Protocol) server established by the terminal on the local IP and the local port.

The terminal is provided with a firewall, and access requests issued by the webpage are all passed through the firewall. The firewall is configured to forward or intercept the data according to the destination address of the received IP data packet. The firewall is configured with an address filtering rule for the designated access address. For example, the address filtering rule may be: converting the destination address of the IP data packet having a destination address as the designated access address (such as 1.2.4.3) to the local IP address and the local port number.

The local IP address and the local port number may be preset or modified by the terminal. For example, the local IP address may be 127.0.0.1, and the local port number may be 8347, the specific content of which is not limited in the present embodiment of the present disclosure.

For example, when the terminal firewall detects that the destination address of the IP data packet that receives the access request is the designated access address 1.2.4.3, according to the address filtering rule configured for the firewall, the local IP address 127.0.0.1 and the local port number 8347 corresponding to the designated access address are acquired. The destination address of the IP data packet is converted from 1.2.4.3 to 127.0.0.1:8347. Afterwards, the IP data packet is sent. Since the converted destination address of the IP data packet points to the local webpage service, after the conversion of the destination address, the access request of the webpage may be successfully to the local webpage service.

In step 204, based on the interaction between the local web service and the operating system of the terminal, the access request is responded to and a response message is returned.

In some embodiments, after receiving the access request, the local webpage service resolves the access request, and determines that the access request is required to perform an interaction operation with the operating system of the terminal. The local webpage service performs the interaction operation, and feeds back the execution result as the response message.

The interaction operation may include reading an application list of the operating system of the terminal, reading local contact information, turning on the camera, turning on the microphone, and other operation that may be performed only based on the operating system of the terminal. The embodiment of the present disclosure does not limit the type of the interaction operation.

The local webpage service returns a corresponding execution result for different interaction operations. For example, when the interaction operation is reading an application list of the operating system, the execution result is returning a retrieved list of applications. When the interaction operation is turning on the camera, the execution result is turning on successfully or failure in turning on.

Returning a response message is sending the response message to the webpage.

In step 205, when the firewall detects that a source address of the response message is the local IP address and the local port number, the response message is redirected to the webpage.

In some embodiments, the process of redirecting the response message to the webpage includes: changing a source address of the response message to the designated access address according to an address filtering rule of the firewall; and forwarding the response message with the changed source address to the webpage. The initial source address of the response message is the local IP address and the local port number.

The response message sent by the local webpage service is in a form of an IP data packet, and the IP data packet of the response message also has to pass through the firewall. The firewall is configured with an address filtering rule for the local webpage service. For example, the address filtering rule may be: converting all source addresses of IP data packets having source addresses as the local IP address (such as 127.0.0.1) and the local port number (such as 8347) to the designated access address. The IP data packet with the converted source address is sent to the browse component. When the browse component detects that the source address of the IP data packet is the designated access address, determines that the IP data packet is a response message returned to the webpage, and forwards the IP data packet to the webpage, specifically to the script js of the webpage.

For example, when the firewall of the terminal detects that the source address of the IP data packet of the received response message is the local IP address and the local port number 127.0.0.1:8347, according to the address filtering rule configured for the firewall, the designated access address 1.2.4.3 corresponding to the local IP address 127.0.0.1 and the local port number 8427 is acquired. The source address of the IP data packet is converted from 127.0.0.1:8347 to 1.2.4.3. Afterwards, the IP data packet is sent. The source address of the response message after the source address conversion is the designated access address, and when the browser identifies that the source address is the designated access address, the browser determines that the response message is information that the webpage interacts with the operating system of the terminal, and then returns the response message successfully to the webpage. Thereby, it can realize the interaction between the webpage and the operating system of the terminal.

It should be noted that the designated access address mentioned above may also be replaced by a designated access address and a designated port number. The designated port number may be set or modified by the terminal. For example, the designated port number may be 80, 5678, etc., which is not limited by the embodiment of the present disclosure.

In the method provided by the embodiment of the present disclosure, when an access request sent by a web page to a preset domain name is received, the preset domain name is resolved into a designated access address that has not been occupied. The access request with a destination address being the designated access address is redirected by a firewall to a local web service which may interact with the operating system of the terminal. Then, the interaction with the operating system of the terminal is performed by the local web service. Such information interaction process can avoid the limitation of the interaction function between the browser or the browser kernel and the operating system, enable interaction between the developed function of the web page and the operation system through a generic browser or software based on the browser kernel, which can lower the developing cost and have a wide applicability.

In addition, by registering the preset domain name for the access request of the webpage that is required to perform interaction with the operating system, it can avoid the domain name resolution confusion caused by the domain name occupation. By setting the designated access address as a non-existent IP address, it can avoid failure in redirection caused by IP address conflict, and it can improve stability and accuracy in information interaction.

In addition, the firewall redirects the source address of the response message returned by the local webpage service, so that the returned response message can be successfully sent to the webpage, and the information transmission from the operating system to the webpage can be completed. In some embodiments, through the address filtering rule of the firewall, it can implement bidirectional address redirection of the IP data packet from the webpage to the local webpage service and from the local webpage service to the webpage, and by utilizing “disguised” destination address and source address, it can realize two-way communication between the webpage and the operating system.
